Interesting..
I bought an extra remote from cab and yet to install.. interesting to hear that there may be a connection back there? I look forward to hearing the results.. I just parked mine at storage an hour ago or I would go look myself! I am still hung up fearing the drill for the mount!

if there is not a connection back there, here is the wire that splits off from factory connection.. I ordered one myself.. hope I don't need it!
